Error : Use of fullScreenIntent requires the USE_FULL_SCREEN_INTENT permission

Here is the answer

Now wee need to add <uses-permission android:name="android.permission.USE_FULL_SCREEN_INTENT" /> permission in manifest file

Permissions changes for fullscreen intents

Apps that target Android Q or higher and use notifications with fullscreen intents must request the USE_FULL_SCREEN_INTENT permission in their app's manifest file. This is a normal permission, so the system automatically grants it to the requesting app
